What lights should a sedan turn on in a tunnel?

A sedan should turn on its headlights (low beams) in a tunnel. At this time, the low beams and width indicator lights at the front of the car will illuminate, and the brake lights at the rear will also turn on. Since the light inside the tunnel is relatively dim, turning on the headlights can alert vehicles in front and behind to the car's position, ensuring driving safety. Because the light outside the tunnel during the day is intense and glaring, while the light inside the tunnel is relatively weak, there is a period of eye adaptation when entering the tunnel. During this process, the driver's judgment of road conditions can easily be affected. Precautions for driving in a tunnel include: 1. Drive at a steady speed, reduce speed before entering the tunnel, and also slow down when exiting the tunnel. These actions are to allow the eyes to adapt to the changes in light; 2. When driving in a tunnel, try to follow the car in front and avoid overtaking.
As a veteran driver with nearly thirty years of experience, I'd like to talk about turning on lights in tunnels. Once you enter a tunnel, the light dims, and it takes some time for human eyes to adjust. Not turning on your lights is extremely dangerous—others can't see your position clearly. I always prefer using regular headlights, that is, low beams, to illuminate the road ahead without dazzling oncoming drivers. Once, I forgot to turn them on, and it was pitch black inside; I almost hit a parked car ahead, breaking out in a cold sweat. Since then, I've made it a habit to check my lights before entering any tunnel. When exiting, I turn them off as soon as the light improves, avoiding unnecessary battery drain or glare. It's also crucial to maintain a safe distance from the car in front because poor visibility increases the risk of rear-end collisions. During rainy or foggy conditions, turning on lights in tunnels becomes even more important due to increased light refraction, enhancing visibility. Over the years, these details have become second nature—safety always comes first.
Turning on lights in tunnels is crucial for everyone's driving safety and should never be taken lightly. When the light dims, a car without lights becomes virtually invisible, increasing the risk of rear-end or side collisions due to sudden braking. I always switch to the low beam setting, or dipped headlights, to enhance the vehicle's silhouette and minimize collision risks. Avoid using high beams as the intense glare can dazzle other drivers and create hazards. Make it a habit to automatically turn on lights when entering a tunnel and switch them off upon exiting when visibility improves. Safety comes first—this isn't just about me, but also about being responsible for others on the road. Many tunnel accidents stem from improper lighting, with statistics showing a significantly higher accident rate in low-light conditions without proper illumination. Therefore, always pay attention to your vehicle's lighting during daily driving—it protects both you and others on the road.
